Section 2: System Operation

The following section discusses the overall operation of the Profile Series v.N1 Access

Control Lock. Section 3 covers how to configure the system to fit your application.

2.1 Presenting a Proximity Card / Entering a Keypad Code

As mentioned above, the Reader is the device used at the door to gain access.

Depending on the system, the user has the option to enter either keypad data, present a

proximity card or both. The Reader then transmits the keypad and/or card data back to

the Interface Module over the RS-485 wires. The data is processed by the Interface

Module and transmitted to the access control panel. The access control system then

makes the decision whether or not to allow access. If a prox card was presented to the

Reader, the Interface Module transmits the wiegand data directly to the panel. The

Reader can read HID format cards up to 39 bits in length. If a code is entered on the

keypad, the Interface Module sends each keypress individually to the access control

panel in an 8-bit burst. The chart below shows the data for each keypress.

Interface Module.
